GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 590,998, dated October 5, 1897. Application filed April 29, 1895. Serial No. 547,502. (No model.)

To all whom it 7nctz concern:

Be it known that I, LEWIS MILLER, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have in vented certain new and useful Improvements in Automatic Grain-Binders, of which the following is a specification, reference being had to the accompanying drawings, which form a part thereof.

This invention relates to automatic grainbinders, and particularly to the devices used in connection with the tripping andcompressing mechanism whereby in the formation of the bundle certain desirable "and predetermined quantities of grain may be caused to operate the trip-arm to connect the clutch that sets the binder in operation, this tripping device being made adjustable, while the compressingarm, which acts in opposition to the binder-arm, by which it is controlled independent of other devices, is so constructed .and operated as to secure quick action and permit the discharge of the bound bundle at the proper moment entirely free from friction. The com pressing-arm is also made adjustable upon its supporting-spring socket, to which it is secured by a bolt, and this support is so constructed as to admit its yielding independently against the inclosed free spring under the pressure of the grain during the'formation of the bundle.

In the drawings, Figure l is a side elevation taken centrally. Fig. 2 is aside elevation of the same parts shown in Fig. 1, taken from the outside front of the machine. Fig. 3 is an elevation from the inner side, showing the location and construction of the tripping device. Fig. 3 is an interior or end View of the sprocket drive-wheel and also shows the clutch-pawl and its supporting-pivot formed integral therewith and which has its bearing in the drive-pinion. Italso shows the pawlspring that is secured by a pin on the pinion. Fig. 3 is the clutch-point of the pawl. Figs. 4c, 5, and 6 are sectional views of the compressor-supporting arm, which is secured, by

means of bolts, to the binder-frame and pro-' vided with the vibrating switches that support the roller of the swinging compressorbar and a projecting flange on its upper edge above the roller and an enlarged space at the outer end to allow time for the latch to close. Fig. 7 is a side view of the compressor-supporting bar that is pivoted to the projecting heel of the binder-arm. Fig. 8 is a sectional view of same on line 8 8 of Figs. 7 and 9. Fig. 9 is a longitudinal section on line 9 9 of Figs. '7 and 8. Fig. 10 is a detail view of the tripping-arm and its adjustable clutch-tripping fingerand the means of connecting the same.

In the drawings, A represents the main frame or the binder, cast of the-usual form in one piece and provided with lugs or projections for supporting the various parts of the binding mechanism attached thereto.

B represents the main binder gear-wheel, which is actuated by its driving-pinion B, that is loosely journaled on its sleeve'shaft R of sprocket-wheel R.

O is the adjustable binder-arm pitman; D, the binder-arm-actuating crank; E, the (30111- pressor-supporting arm, secured rigidly to the binder-frame; F, the compressor-arm; F, its yielding sliding supportingspringsocket support, to which it is adj ustably secured;v F the locking sliding flange connections on the upper and lower side that hold the lower side of the compressor-supportingspring socket to the compressor-supporting bar H; F the upper locking projection which is formed on the lowerside of the compressor- .arm, forming a guideway and bearing-surface and sliding freely on its supportingbar; f, the adjustable compressor securing bolt, which also holds the parts together. G is the binder-arm; H, the compressor-supporting bar,.pivoted to the binder-arm, and H is its supporting-roller, journaled thereon; H the projecting finger of the compressorarm, that extends under the binder-arm and is locked by contact therewith; H the pivot securing the compressonsupporting arm to the extended heel of the binder-arm.

h is the outer spring support of compressor-supporting bar, formed integral with the bar H.

I represents the concave compressor-supporting latch that is pivoted at I to the compressor-supporting arm and held-in itsstationary place by the spring 0, secured to its projecting pin 1 I is an enlarged roller-space in the rigid compressor-supporting arm E.

I is a projecting flange on arm E above the roller.

J is a vibratable bridge-switch secured in its journal-bearing J by means of its supporting-pivot J and caused to rise by means of the spring 0, secured to its pin J that moves in the slot J in the compressor-supporting bridge.

6 is the fixed portion of the arm E, and supports the compressor-roller H while the bundle is being tied.

O is the compressor-spring, which is placed loosely within the sliding compressor-socket arm F. This compressor-supporting-spring socket within the arm F is free to slide or yield outwardly on its bearings on the arm 11 against the inclosed free spring 0, it being held thereto by hooked locking-groove F on its under side and at the top by the downwardly-extended long base F of the adjustable compressor-arm F and secured thereto by its locking-bolt f.

K is the triparm rock-shaft; L, its adjustable clutch holding and tripping finger; M, the locking-arm, secured to the tripping rocl shaft K; N, the tripping-arm that receives the grain brought against it by the packers in the formation of the bundle.

Zare ratcheted teeth on the finger L, that are locked with the corresponding tooth Z of the locking-arm M.

Z is the pivotal bearing of the finger L, which is attached on the pivot F.

The parts are thus secured and held together by means of the bolt on, that is secured in the hole m of the tripping-finger on the one side and within the slot m of the locking-arm M, by means of which it may be adjusted to any desired position.

L is the clutch-pawl and is secured to the drive-pinion of the binder, it being alternately held out of engagement by means of the tripping-finger L, which is retained in its normal place against the pressure of the grain during the formation of the bundle by means of the sliding boltp, that is provided with an angular projecting hook on which it rests and slides as it is held in position by its spring 4", that permits it to yield within its bearings in its supporting-finger P, that is secured to the binder-arm-actuating crank D.

B is the sleeve-bearing formed integral with the pinion B.

L is the clutching-pawl, having its pivotal supporting-axle L formed integral therewith, which is secured within its bearing in the pinion B.

trepresents the projecting locking-finger of the clutch-pawl; t the clutch ratchet or teeth formed within the sprocket-wheel R; 25, the clutch-pawl-holding spring; 25 its securingpin attached to the pinion B.

The clutch-pawlL, having its axle orpivot L secured Within the pinion B, is caused by its springt', also secured to the pinion, to hold it in contact with the ratchet-teeth t in clutching and starting the binder. The sprocket drive-pinion havinga sleeve-shaft R revolves freely upon its bearing R secured to the main binding-frame, while the pinion Band its sleeve-bearing l3 revolve freely upon the sleeve-shaft R of the sprocket-wheel, and as the clutching-pawl is alternately held out of engagement by the tripping-arm L the binder is unclutched. This sprocket-wheel runs at a high rate of speed under a firm tension of its drive-chain, which produces friction and wear and liability of getting out of line, that is obviated by the broad sleeve-axle bearing projecting through the pinion, which revolves only at stated intervals on said sleeve, thus securing a uniformity of friction and wear.

S is the packer-shaft, provided with the usual packer-cranks S S. The shafts receiving power from the harvester it actuates the binder by means of the drive-chain T and its sprocket-wheels R R and the gear connected therewith.-

' The drawings thus fully illustrate my binder, which forms the subject of many prior patents and applications not referred to in the present case, and enables me to show the operation of myimproveinents in connection with the general structure, and as the desired movement is imparted to the packershaft S (see Fig. 3) the packer-fingers (not shown) that are mounted on the revolving crank-arms S S gather the grain from the harvester-elevator and force it down on the trip-arm N and gradually cause it to rock its shaft K and move the clutch-trip finger L against the stress of the spring-finger P, and gradually force its upper end from contact with the clutch-pawl L, which is then forced by its spring to clutch in connection with a ratchet-tooth formed within the contin uouslyrunning sprocket wheel R, and thereby clutch and set the binder in motion, the pinion B causing the main binder-wheel B to revolve. The binder-arm pitman 0 being attached thereto will cause the binder-arm-actuating crank D and the binder-arm G to rise in the receptacle in the formation of the bundle, while [he compressor-supportingbar H, that is pivoted to the projecting heel of the binder-arm, will be drawn forward with its compressor F and compress the bundle in connection with the binder-arm G.

At its initial movement the compressor-supporting bar H is sustained by its supporting roller H, which rests on the stationary supporting-latch I, as shown in Figs. 4 and 9.

It will be observed that I provide a large space in the compressor-supporting arm E above the roller at this point to accommodate the roller of the compressor-arm to different positions which are required in the various adjustments of the binder-arm pitman that will cause the binder-arm to act upon the projection H and rock the compressor-supporting bar on its pivot H to change the position of the roller H and to allow time for the latch to close, the entire length of said supportingarm E having a flange projecting inwardly over the roller-way, which is very important to prevent the roller from rising out of place. As the compressor-arm is drawn forward it ICC IIC

will come in contact with the compressor-sup porting bridge J, as shown in Fig. 5. This bridge will assume a horizontal position and permit the roller to pass over it onto the fixed portion 6 of the arm E, where it rests during the tying of the bundle, and the spring secured to the arm J 3 in the slot J will cause the bridge J to rise and assume a vertical position, and when the binder-arm opens it will cause the compressor-supporting bar H audits supporting-roller H to move outward and oif the bridge 6, as shown in dotted lines, Fig. 6, and thus fall out of the Way to permit the discharge of the bundle during the opening of the binder-arm, and as the binder-arm opens down beneath the binder-table it will come in contact with the projecting finger H of the compressor-arm and thus form a lockhinge joint, which Will cause the compressorarm and its supporting-roller H, attached thereto, to rise, as shown in Fig. 2, at which time the roller is brought in contact with the supportinglatch I, as shown in Figs. 2 and 6, and cause it to rock out on its pivot I, and its momentum will bring the roller in contact with the upper flange, and as it falls back the roller H Will enter the concave surface of the same, as shown in Figs. 1 and 4, when the latch will swing inwardly to its normal stationary position to receive and support the compressor-arm at this point during the formation of the bundle.

It is often desirable in dilferent kinds of grain to enlarge the capacity of the bundlereceiving chamber, as in some conditions of grain the bundle requires and admits of more compressing than in other conditions, and in order to readily adapt the binder-receptacle to this capacity it is necessary to adjust the tripping-finger N to vary the time of its operation by means of a predetermined quantity of grain to causethe clutching and starting of the binder at the proper moment, suitable to these varying conditions of grain. I accomplish this adjustment in the following manner: The slotted locking-arm M, being seen red to the tripping rock-shaft K, is provided with a locking-tooth Z, and the clutch holding and tripping finger L, provided with a pivotal bearing Z journals upon the projecting end Z of the shaft K. This clutch-tripping linger having serrated teeth Z at its lower end beyond its pivot is secured at any desired position upon the locking-arm M by means of its bolt m, and can be read clutching-pawl L in an unclutched position,-

and when moved from contact with the pawl as the binder is clutched and put in operation the spring-supportin g finger will carry it up ward and rotate the rock-shaft K to depress the tripping-arm N beneath the binder-table as the bundle is discharged.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-

1. The compressor-supporting arm pivoted to the binder-arm and provided with its pro jecting finger H and its supporting-roller 11 combined with the rigid arm E, its flange Ii. above said roller-Way its supportinglatch I pivoted at I and its vibratable bridge-switch J secured in the journal bearing J by means of its supporting-pivot J and the spring 0' connecting said latch and switch and operating substantially as set forth and described.

2. The compressor-supporting bar H its locking-flanges F combined with the corn pressor-arm F secured thereto by means of its sliding adjustable projection F on the lower side thereof and the spring-socket arm F provided with guideways and the intermediate free spring 0 substantially as shown and described.

3. In a grain-binder the vibrating compressor supporting bar H, its supportingroller H, its actuating-finger H its supporting-pivot H the'concave spring-receptacle, the end spring supporting-wall h, and the locking sliding flange F combined with theyielding sliding socket F, the intermediate inclosed spring 0, the adjustable securedl compressor-arm F and its locking-flange F and seen ring-boltfsubstantially as described.
